Ayurveda (Dosha System)

Ayurveda ('knowledge of life' in Sanskrit) is the traditional medical system of India, spanning over three thousand years and still officially recognized as a healthcare system in India and Sri Lanka. Its foundational texts — the Charaka Samhita and Sushruta Samhita — were composed in the early centuries of the common era but draw upon a considerably older oral tradition. At its core lies the concept of three doshas — bioenergetic principles governing all processes in the living organism.

The three doshas are formed from five panchamahabhuta (great elements): Vata (wind + ether) governs movement, respiration, and the nervous system; Pitta (fire + water) governs digestion, metabolism, and intellect; Kapha (earth + water) governs structure, immunity, and stability. Individual constitution — prakriti — is determined by the ratio of doshas at birth and remains unchanged. The current state — vikriti — reflects present imbalances caused by lifestyle, diet, season, and psychological condition.

Diagnosis in Ayurveda includes pulse diagnosis (nadi pariksha), examination of the tongue, eyes, and skin, and a detailed inquiry into habits, preferences, and symptoms. Treatment targets not the disease itself but the restoration of dosha balance: diet, lifestyle, herbal preparations (rasayana), purification procedures (panchakarma), and meditative practices. Each season and time of day is also associated with particular doshas, making Ayurvedic diagnosis a continuous dynamic process.

In the Errarium atlas, the dosha system is classified as a somatic method with diagnostic and navigational function. It is related to the Wu Xing system in traditional Chinese medicine (#25) — both work with elemental principles and balance as the foundation of health — yet the ontology, elemental sets, and interpretive logic differ fundamentally. Ayurveda is unique in integrating physiology, psychology, and spiritual practice into a single system.
